The correct answer is C. Both 1 and 2.
The Shaka were a group of Indo-Scythians who ruled parts of India from the 2nd century BCE to the 4th century CE. They were known for their military prowess and their contributions to Indian culture.
One of the most significant contributions of the Shaka was their promotion of trade. They established a number of trade routes, including one that connected Gujarat with the Mediterranean Sea. This trade route helped to bring prosperity to Gujarat and to introduce new ideas and technologies to India.
The Shaka also issued a large number of silver coins. These coins were used to facilitate trade and to pay taxes. They are also an important source of information about the Shaka period.
In conclusion, the Shaka rule gave rise to trade in Gujarat through sea and they issued a large number of silver coins. Both of these contributions had a significant impact on Indian history.
